A spokesman for the Pasco County Sheriff's Office said Mariesa Weber's death was not suspicious. Family members said they believe she fell over as she tried to adjust the plug of a television behind the bookshelf.

Weber, 38, returned home Oct. 28 and greeted her mother, then was not seen again. Her family thought she had been kidnapped and contacted authorities. Family members scoured her room for clues but found nothing, though they did notice a strange smell.

Late one night Weber's sister went into her bedroom and looked behind a bookcase, where she saw the woman's foot. Using a flashlight the family saw Weber was wedged upside-down behind the unit.

"I'm sleeping in the same house as her for 11 days, looking for her," her mother, Connie Weber, told the St. Petersburg Times. "And she's right in the bedroom."

Both Weber and her sister had previously adjusted the television plug by standing on a bureau next to the shelf and leaning over the top. Her family believes Weber, who was 5-foot-3 and barely 100 pounds, may have fallen headfirst into the space.

"She's a little thing," her mother said. "And the bookcase is 6 feet tall and solid. And she couldn't get out."

The sheriff's office said Weber appeared to have died because she was unable to breathe in the position she was in.
